Detailed Description
A Bernoulli random number distribution.
Generates a sequence of true and false values with likelihood $ p $
that true will come up and $ (1 - p) $ that false will appear.

Constructor & Destructor Documentation
std::bernoulli_distribution::bernoulli_distribution (double __p = 0.5)
[inline, explicit] Constructs a Bernoulli distribution with likelihood
p.
Parameters:
__p [IN] The likelihood of a true result being returned. Must be in
the interval $ [0, 1] $.
Definition at line 1702 of file tr1_impl/random.
Member Function Documentation
template<class _UniformRandomNumberGenerator > result_type
std::bernoulli_distribution::operator() (_UniformRandomNumberGenerator
& __urng) [inline] Gets the next value in the Bernoullian sequence.

bernoulli_distribution random number distribution __x into the output
stream __os.
Parameters:
__os An output stream.

bernoulli_distribution random number distribution __x from the input
stream __is.
Parameters:
__is An input stream.
__x A bernoulli_distribution random number generator engine.
Returns:
The input stream with __x extracted or in an error state.
